Rufus USB

Rufus is a small program for converting a normal flash drive into a complete bootable USB from which you can directly start in DOS.

Configuring the program is as simple as inserting the device you want to format, marking the options you want, and clicking “start.” In just a few seconds your new bootable USB for DOS drive will be ready.

Rufus is a very small, light, helpful, and easy-to-use tool. If you need to start your computer in DOS for whatever reason, this is one of the best ways.
